啟發式

启 = 口 + 户 : The Queen of Hearts (qi) is informing (启) every member on the space station that from now on she has to be greeted with 启奏万岁 whenever someone wants to see her in the space station (Ø3). Furthermore, anyone visiting her has to bring a mandarin (口) as a present. She writes this rules down in orange on a wooden swinging door (户) so that no-one forgets.

式 = 工 + 弋 : I'll use a specific style as mnemonic symbol: 哥特式, gothic.

Sherlock Holmes and the goth are celebrating a Viking festival in the space station's bathroom. They don't have trunks to throw around, so they use a steel beam. They also celebrate by practising archery. In zero gravity it is easy for them to set one world record after the next.
